STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent NO. 401,815, dated April23, 1889.

Application filed November 28, 1887- Serial No. 256,320}-- (No model.)

(tZZ whom it may concern:

Be it known that 1, CASPER BOHNENSTIEL of Newport, in the county ofCampbell and State of Kentucky, have invented certain new and usefulImprovements in atches, of which the following is av specification.

The several features of my invention and the advantages arising fromtheir use, conjointly or otherwise, will be apparent from the followingdescription.

In the accompanying drawings, forming part of this specification, Figurel is a face view of so much of the works of a watch as is necessarytoillustrate my invention, the parts being in position forwindingand thesecondshand arbor arranged for a hunting-case watch. Fig. 2 is a sectiontaken at the line .r :c, Fig. 1. Fig. 3 is a view similar to Fig. 1, butshowing the parts arranged to set the hands and the seconds-hand arborin position for an openface watch. Fig. is a view of the outer face ofthe dial-plate removed from watch. Fig. 5 is a view of the inner face ofthe dial-plate. Fig. (3 is a perspective view of the seconds hand arborand the detachable pinion connected therewith. Fig. 7 is a verticalsection, on an enlarged scale, of the arbor and pinion of theseconds-hand The lever A is fulcrumed at a. Immediately under the leverA, and loosely centered on its fulcrum, is the wheel B,which is providedwith teeth which project from its edge and are preferably beveled ontheir under surface. The teeth I) mesh with the teeth of the pinion Oand D, one on each side. Both of thepinions C and D are centered looselyon arbors attached to the lever A, and are carried with the lever A inits movements. The lever A terminates in the cam-tip A. It is alsoprovided with a lug, a, against which the spring 6 bears, and tends tomove the lover into the position occupied in Fig. 1.

The wheel B meshes with thebeveled wheel F, which latter is mounted onthe squared end g of the stem G, and is moved by it. The end 9 of thestem G is made long enough to allow the stem to be pushed in and out andAn annular still remain in the wheel F. groove, g, is cut in the stem Gand receives the pin 71, projecting downwardly from the pawl H. The pawlH is centered at 7t and terminates in a oanrtip, 7L2, which bearsagainst the cam-tip A of the lever A. lVhen the stem G is moved in orout, it imparts a cor responding movement to the pawl H through themedium of the pin h. \Vhen the parts are in the positions shown in Fig.1, the stem G is in. If now it be drawn out, it moves the pawl H intothe position shown in Fig. 3, eitecting simultaneouslythe change shownin the position of the lever A. iVhen the stem is pushed in, the pawl His returned to its former position and the spring 6 forces the lever Aback to its first position. hen the lever A is in the position shown inFig. 1,the wheel C meshes with the wheel I, which winds the spring,while the wheel D is free, except as it meshes with the wheel B. hen thelever A occupies the posit-ion shown in Fig. 3, the wheel C is free andthe wheel D meshes with the wheel J, which is otherwise geared to setthe hands; hence to wind the watch the stem G is forced in, by whichmovement the mechanism for winding is brought into gear, when by turningthe stem the watch may be wound. To set the hands, the stem G is drawnout slightly. This throws the wheel D into gear with the setting-wheel Jand enables the hands to be moved by the stem G.

Among the train of wheels for operating the hands is the largefourth-wheel K of the watclrmovement, which meshes with the pinion L ofthe seconds-hand arbor Z. The arbor Z is rigidly attached to the pinionL and projects from it in its axis. The arbor l passes through the capL, and is swiveled therein by means of the arm Z, which fits in thegroove Z in the arbor. The cap L preferably has a rabbeted edge, whichholds it in place in the plate H. The plate M-has the two openings N andN, each with rabbeted edges. These openings are located, one on the linepassing through the stem and the center of the watch and the other onthe line drawn at right angles to this first line at the center of thewatch. The device illustrated in Fig. 6 may be set in either one ofthese openings, and in both positions the pinions L will gear with thewheel K. The dial-plate P is provided with four parts, 1), which arereceived in four corresponding openings, 1), in the plate M. Thedial-plate also has a central opening, 11 through which the arbors ofthe hour and minute hands pass,

and an opening, 19 for the arbor of the seconds-hand.

In all Watches the seconds-hand is immediately opposite the twelve ofthe dial; but the position of the dial differs in hunting-case andopen-face watches. In the latter the twelve is placed at the stem, andin the a former the three is placed at the stern. In

in number and equidistant, the plate may be used for either style ofcase.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of the plate M, having openings N N, fourth-wheel K,and detachable seconds-hand arbor and pinion, substantially as and forthe purposes set forth.

2. The combination of plate M, having openings N N, fourth-wheel K, capL, pinion L, and arbor Z, swiveled in cap L, substantially as and forthe purposes specified.

3. The combination of plate M, having openings N N, with rabbeted edges,and openings 19 p p p, seconds-wheel K, cap L, with rabbet-ed edges,pinion L, arbor Z, swiveled in cap L, and dial-plate P, having fourposts, p, substantially as and for the purposes specified.
